Product Description



1) Composite pipe is a five-layer composite pipe, taking the overlap-welded aluminum alloy layer as the core layer which is tightly bonded with an intermediate adhesive to the inner and outer layers of Hi-Density or Cross-Linking polyethylene. All the five layers are extruded in one step by ultrasonic.

2) Combines all the advantages of metal pipe and plastic pipe but eliminates the disadvantages of both materials at the same time. The aluminum core is absolutely diffusion tight; It reliably prevents oxygen or gases from permeating into pipe.

3) Antikorrosionseigenschaft: Bei normaler Temperatur kann es allen Arten von Säure-, Alkali- und Salzlösungen standhalten.

4) Low thermal conductivity: Thermal conductivity is 0.45w/M. K, about 1/100 of that of steel pipe, it owns good performance of heat preservation.

5) Niedrige Wärmeausdehnung: Der Wärmeausdehnungskoeffizient beträgt 2,5 × 10–5 m / m. K, nur 1/8 desjenigen von PE-Rohren, entspricht weitgehend dem von Aluminium

6) Besserer Fluss: Die innere Rauheit unseres Rohrs beträgt 0,007 mm. Glatte Innenwand, keine Ablagerungen, der Durchfluss beträgt mehr als 30% des Durchflusses desselben Metallrohrs

7) Freely bent by hand without tools, making the use of numerous fittings unnecessary. Our pipe can be directly installed up to 200meters without any fittings. It works well in a wide range of temperature from -40 centigrade to 95 centigrade.
